Artem Ponomarenko

Data Analyst · Germany

I turn messy data into insights that actually get used — large-scale analytics, ETL pipelines, and experiments at the scale of billions of records.

With a background in applied math and ML, I run A/B tests, build forecasts, and fix the data pipelines that keep breaking.
